一类弱相依随机变量的渐近结果

Asymptotic results for certain weak dependent random variables

Idir Arab, Paulo Eduardo Oliveira

摘要:

本文考虑一类特殊的弱相依随机变量,其Lipschitz变换的协方差是受控的。这一类包括但不限于正相关变量、负相关变量和其他几类弱相关结构。我们证明了一个强大数律的收敛速度,这是几乎最优的,在这个意义上说,它是任意接近的最优率为自变量的表征。此外,我们证明了一个不等式比较的联合分布与产品分布的利润,类似于著名的纽曼不等式的特征函数的相关变量。作为结果,我们证明了一个中心极限定理及其对应的函数,并证明了这类弱因变量的经验过程的收敛性。

英文摘要:

We consider a special class of weak dependent random variables with control on covariances of Lipschitz transformations. This class includes, but is not limited to, positively, negatively associated variables and a few other classes of weakly dependent structures. We prove a Strong Law of Large Numbers with a characterization of convergence rates, which is almost optimal, in the sense that it is arbitrarily close to the optimal rate for independent variables. Moreover, we prove an inequality comparing the joint distributions with the product distributions of the margins, similar to the well-known Newman's inequality for characteristic functions of associated variables. As a consequence, we prove a Central Limit Theorem together with its functional counterpart, and also the convergence of the empirical process for this class of weak dependent variables.
